CAN-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 612,031, dated October 11, 1898.

Application filed August 23, 1897.

To all whom it may concern:

Be it known that I, WILLIAM J. GORDON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Can-Heading Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to can-heading and metal-jointing machines; and it consists of improvements therein in various details whereby the efficiency thereof is greatly increased.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and pointed out in the claims.

Figure 1 represents a side elevation of a can-heading and metal-jointing machine embodying my invention. Fig. 2 represents, on an enlarged scale, a side elevation of a bracket, showing a slot therein for the reception of an end of an operating-lever. Fig. 3 represents a perspective View of an end of the operatinglever. Fig. 4 represents a side elevation of the operating-lever, showing also its support and the formers carried thereby. Fig. 5 represents a section on line a: 00, Fig. 4.. Fig. 6 represents the operating-lever shown in section and a stop against which a dog carried by said lever is adapted to abut. Fig. 7 represents a perspective view of a detachable frame upon which certain of the operative parts of the machine are supported. Fig. 8 represents a section on line y y, Fig. 1. Fig. 9 represents a section on line .22, Fig. 1. Figs. 10, 11, and 12 represent, on an enlarged scale, the different positions the formers assume relative to the can during the steps of heading the same. Figs. 13, 14., and. 15 represent, respectively, the initial, secondary, and final steps in the heading of a can.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a can-heading and metal-jointing machine, the same consisting'of a framework or housing 2, having at the lower portion thereof the treadle 3, which is fulcrumed at 4lto anysuitable fixed point.

5 designates a link having one end pivotall y Serial No. 649,265. (No model.)

secured to the treadle 3, while at or near its other end is attached the lever 6, said link 5' having a plurality of openings 5 therein for the purpose of adjustment. The lever 6 is fulcrumed at 7 to a suitable portion or extension 8 of the housing 2, said extension being provided with a plurality of openings 9, also for the purpose of adjustment, as will be explained.

1O designates a spring which is secured to the lever 6 and to a pin or projection 11 of the housing 2, the function of said spring being to restore the treadle to its normal position when the foot of the operator is removed therefrom.

12 designates a head carried by the lever 6, said head having a seat 13 therein, which supports the spindle 14., said spindle being rotatably mountedin the sleeve 15, which is carried by the arm 16, the latter projecting from the housing 2. o

17 designates a threaded stem engaging the arm 16, the lower end of said stem being adapted to abut against the lever 6 near the end of its movement, and thus form an adj ustable stop therefor.

18 designates a rest through which a portion of the spindle lt passes, said rest supporting thereon the collar 19, to which is attached the platform 20, which latter is adapted to support a can 21 thereon, said rest being sustained by meansof the arm 22, which moves on suitable ways 23, located on the sleeve 15, and is held at the desired height by means of the bolt or other fastening device 24. The device for holding the head of the can in place and for rotating the can is seen at the upper portion of Fig. 1 and consists of the head 25, which is removably secured to the spindle 26 bya set-screw or other suitable device and carries a plate 25 it being noticed that said head 25 and plate 25 can be removed, so that difierent sizes may be attached, depending on the size of the can that is to be headed. The spindle 26 has 5 suitable bearings in the upper extensions 27 and 28 of the housing 2.

29 designates a'bevel-gear mounted on the spindle 26 and meshing with the gear 30, which latter is secured to the shaft 31, which is provided with suitable bearings and tight and loose pulleys, as is customary.

designates a frame supported on the housing 2, said frame consisting of the sides 33 and 34 and the end portions and 36, the latter having an opening 37 therein, in which is seated the stem 33, carrying collar 39 in which the lever 39 is oscillatorily mounted, the latter thus being fulcrumed in said end portion 36, and said stem being held in position by means of a nut or other suitable fastening device 36 40 designates a slot in the side of the frame 32, through which passes the tightening-bolt 41, which engages the housing 2, by means of which bolt the frame 32 is locked in the desired position, the adjustment of the frame being effected by means of the threaded stem or screw 42, which engages a threaded opening in the end 35, said stem having its extremity 43 swiveled or otherwise secured to the housing 2, as will be best understood from Fig. 8, whereby it will be apparent that when the bolt 41 is loosened the rotation of the stem 42 will cause the frame 32 to travel in the desired direction.

44 designates a projection on the side 34, having the stop device 45 passing therethrough, the same consisting in the present instance of a threaded stem having lock-nuts thereon, said stem serving to limit the movement of the lever 39 and to cause a slight rotary movement to be imparted thereto by the contact of the dog 46 therewith, said dog being secured to said lever by a set-screw or other device. It will thus be seen from the foregoing that the lever 39 is capable of a plurality of oscillatory movements, said lever oscillating axially as well as bodily, as has been above explained.

47 designates a bracket attached to the side 33, said bracket having therein the laterally-extending slot 48 for the reception of the flattened end or tongue 49 of the lever39.

The slot 48 extends laterally for a portion of its length and terminates in the upwardly extending or inclined slot 50, the function of which will be hereinafter explained.

51 and 52 designate screws located near the terminals of the slots 48 and 50, respectively, said set-screws serving to limit the movement of the lever 39. Upon the lever 39 between its fulcrum and the bracket 47 is secured the collar 53, which latter has the upper and lower arms 54 and 55, respectively, projecting therefrom, the lower arm carrying the former 56, which has the conical working face 57, by means of which the initial step of heading a can is performed.

58 designates a lug pivotally attached to the arm 54, said lug depending from the swiveled head 59, in which the former (i0 is rotatably mounted, the latter having the working face 61, between which and the face (52 of the former 56 the second step of headinga can is performed.

63 designates a spring interposed between the head 59 and the extension 6-1 of the arm 54, whereby the former 60 is always retained in proper position after the operation.

(35 designates an arm mounted on the collar 53 and curved upwardly over the head 59, the portion of said arm having apin (56 passing therethrough, the head of which pin is seated in the swiveled head 59, while its other extremity bears normally against the portion [57 of the extension 27 of the housing, it being evident that a continued movement of the lever will carry the pin 66 into contact with the cam or inclined face 68, and thus depress the head 59 and the former 60 at the proper period.

69 designates the former by means of which the final step of heading a can is performed, said former consisting of a disk having a substantially rectangular edge and supported upon the lever 39 at a point intermediate the handle thereof and its fulcrum.

In Figs. 13 to 15 are shown portions of a can in the act of being headed. In Fig. 13 the head 70 has the depending portion 71, which overhangs the flaring contiguous edge 72 of the can. After the initial step the portion 72 is given a pronounced lateral deflection, as seen in Fig. 14, the same being new designated as 73, while the overhanging portion 71 engages the same, as indicated at 74 and 75, the portion 76 engaging the side of the can.

In the final step of heading the can, as seen in Fig. 12, the portion is forced tightly against the portion 76, the parts now appearing as seen in Figs. 12 and 15.

The operation of the machine in detail is as follows: The parts of the machine are adjusted to the height and size of the can to be headed by raising or lowering the rest 18, so that the platform 20 will be sustained at the proper height relative to the formers, and the threaded stem or stop 17 is adjusted to the desired extent, as are also the lever 6 and the link 5 by means of the openings 5 and 9. The belt 41 having been loosened, the frame 32, carrying the formers and operating-lever, can be adjusted relative to the can by the proper manipulation of the screw 42, after which the bolt 41 is tightened again. Rotation having been imparted to the shaft 31 through the medium of the intermediate gearing the plate 25 will be revolved, and the can, with its head 70, having been placed on the platform 20, will be raised by the depression of the treadle, and the contact of the plate 25 with said head will cause said can, platform, and rod or lower spindle 14 to revolve. The attendant now moves the lever 39 in the proper direction, whereupon the former 56 is brought against the overhanging portion 71 of the can-head in substantially the manner indicated in Fig. 10, it being understood that the tongue 49 is now moving in the laterally-extending groove 48. At about the instant the tongue 49 reaches the inclined groove 50 the dog 46 strikes the stop 45, thereby imparting a slight rotary movement to the lever 39, the latter being rotatable in the collar 39 whereupon a rotary movementis imparted to the former 56, so that the latter assumes the position seen in Fig. 11. At about this instant the pin 66 (seen in Figs. 1 and 10) strikes the inclined face 68, the former 60 is forced downwardly, and the former 56 is forced upwardly, the formers 60 and 56 now appearing as seen in Fig. .11, and the canhead and contiguous portion of the can appear as seen in Fig. 14. Areverse movement is now imparted to the lever 30, and the formers 60 and 56 separate in the direction indicated by the arrows in Fig. 11, and a continued reverse movement of the leverbrings the former 69 into the position relative to the can, (seen in Fig. 12,) and the operation of heading the can is completed, as has already been explained, the can now appearing as seen in Fig. 15.
